How To Detect Bunions

Overview
A bunion is generally considered as an enlargement of the joint (a lump of bone) at the base and side of the big toe (specifically, the first metatarsophalangeal joint). Bunions form when the toe moves out of place. As the big toe bends towards the others this lump becomes larger and the bunion can become painful, arthritis and stiffness can eventually develop. Hallux valgus or hallux abducto valgus (HAV) is the name used for the deviated position of the big toe and a bunion refers to the enlargement of the joint, most of the time the two go together and can just be referred to as 'bunions'. The word bunion is from the Latin "bunion," meaning enlargement.

Causes
Women are particularly at risk for bunions, as high heels may help aggravate the condition. Bunions may also be caused when bursal sacs, sacs that absorb friction and lubricate the many tendons, bones muscles of the body, in the foot become inflamed or swollen. Bunions may also be prompted by the metatarsal bone, the bone that runs from the heel to the toe of the foot, with one metatarsal bone leading to each toe, of the big toe enlarging or deviating slightly to the outside of the foot.

Symptoms
Bunions starts as the big toe begins to deviate, developing a firm bump on the inside edge of the foot, at the base of the big toe. Initially, at this stage the bunion may not be painful. Later as the toes deviate more the bunion can become painful, there may be redness, some swelling, or pain at or near the joint. The pain is most commonly due to two things, it can be from the pressure of the footwear on the bunion or it can be due to an arthritis like pain from the pressure inside the joint. The motion of the joint may be restricted or painful. A hammer toe of the second toe is common with bunions. Corns and calluses can develop on the bunion, the big toe and the second toe due to the alterations in pressure from the footwear. The pressure from the great toe on the other toes can also cause corns to develop on the outside of the little toe or between the toes. The change in pressure on the toe may predispose to an ingrown nail.

Diagnosis
The doctor considers a bunion as a possible diagnosis when noting the symptoms described above. The anatomy of the foot, including joint and foot function, is assessed during the examination. Radiographs (X-ray films) of the foot can be helpful to determine the integrity of the joints of the foot and to screen for underlying conditions, such as arthritis or gout. X-ray films are an excellent method of calculating the alignment of the toes when taken in a standing position.

Non Surgical Treatment
Treatment may be surgical or non-surgical. The goal of non-surgical treatment is to relieve pressure on the foot and to prevent pressure sores and foot ulcers. This is accomplished by prescribing accommodative shoes with a wide toe box - sandals or extra depth shoes with soft moulded insoles. It may also be possible to relax the leather on shoes to make room for a bunion.

Surgical Treatment
An operation may be advised if a change of footwear does not ease symptoms. The aim of the operation is to straighten the joint as much as possible and relieve pain. It is not usually done just to improve appearance. It can be done using a local or a general anaesthetic and you are usually out of hospital the same day. The operation chosen by the specialist depends on the severity of the bunion, the shape of your foot, and other factors, such as if you have arthritis in the joint. There are many different types of operation which are used to treat bunions. These range from operations to trim parts of the joint, to a total artificial replacement of the big toe joint (similar to a knee or a hip replacement). A common surgical procedure used is called a scarf osteotomy (osteotomy means a cut in the bone). An operation is usually successful at easing symptoms, but not in all cases. It is not always possible to relieve the pain completely or make the toe perfectly straight. Your specialist will be able to advise on the pros and cons of surgery, and the success rate of the chosen operation. Continued pain, infection and the bunion returning are some of the complications of surgery of which you need to be aware. You will need to continue to wear sensible, wide-fitting shoes for six months after the operation.
